Speak to Experts

CVE-2026-7458 represents a critical vulnerability affecting the User Verification by PickPlugins plugin for WordPress, confirmed in all versions up to and including 2.0.46. The vulnerability arises from the use of a loose PHP comparison operator in the "user_verification_form_wrap_process_otpLogin" function, which fails to properly validate OTP codes. This flaw can be exploited by unauthenticated attackers, enabling them to log in as any user with a verified email address, including administrators, by submitting a "true" OTP value.

The CVSS score for this vulnerability is 9.8, classifying it as critical. This high score indicates a significant threat to the confidentiality, integrity, and availability of affected systems. Organizations utilizing this plugin are at risk of unauthorized access and potential data breaches, as attackers may easily bypass authentication mechanisms.

Given the severity of this vulnerability, organizations should prioritize patching immediately. Failure to address this issue could result in unauthorized access to sensitive information and further compromise of the affected systems.

Currently, there are no known exploits or public proof-of-concept code for this vulnerability. However, the risk is significant, and organizations should remain vigilant while awaiting a vendor patch.

Vulnerability Details

The User Verification by PickPlugins plugin enables user verification via OTP codes, but its flawed implementation poses a threat to user accounts. The loose comparison in the OTP validation process allows attackers to bypass authentication, effectively gaining access to any account associated with a verified email address.

The CWE classification for this vulnerability is CWE-288, indicating an authentication bypass issue. This vulnerability was published on May 2, 2026, and organizations must act swiftly to mitigate its impact.

Technical Analysis

The root cause of CVE-2026-7458 is the improper use of a loose PHP comparison operator in the OTP validation function, which fails to enforce strict type checking. This allows attackers to manipulate the input and gain unauthorized access to user accounts.

The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely without physical access to the target system. The complexity of the attack is low, requiring no special privileges or user interaction. As a result, this vulnerability is particularly dangerous, given its potential for widespread exploitation.

The attack impacts confidentiality, integrity, and availability, as unauthorized access could lead to data leaks and system compromise. Organizations must therefore monitor for any suspicious activity and prepare for potential exploit attempts.

Risk & Impact Analysis

The risk to organizations includes the potential for unauthorized access to sensitive information and disruption of services. The blast radius could extend significantly, affecting not only individual accounts but also the integrity of the entire site.

Given the critical CVSS score of 9.8, organizations should address this vulnerability in their priority patch cycle. The urgency is heightened by the possibility of attackers leveraging this flaw to gain administrative access, leading to potential data breaches.
